Recent forecasts indicate a cold front advancing from the southwest into Buenos Aires on August 17, shifting winds southerly and driving a progressive temperature drop after milder conditions on the 16th. Model guidance and climatological context for late winter in the region support daytime maxima clustered near 13–15 °C, consistent with the market’s heaviest volume on those bins. Typical August highs average 16–17 °C, but the frontal passage introduces cooler maritime air that limits diurnal warming and keeps peak readings below seasonal norms. No major model disagreements have emerged in the latest runs, though minor variations in front timing could still nudge the daily maximum by 1 °C.
